Crate const_hex

  

This crate provides a fast conversion of byte arrays to hexadecimal strings, both at compile time, and at run time.

Extends the hex crate’s implementation with const-eval, a const-generics formatting buffer, similar to itoa’s, and more.

Version requirement: rustc 1.64+

Structs

• Buffer
  A correctly sized stack allocation for the formatted bytes to be written into.

Enums

• FromHexError
  The error type for decoding a hex string into Vec<u8> or [u8; N].

Constants

• HEX_CHARS_LOWER
  The table of lowercase characters used for hex encoding.
• HEX_CHARS_UPPER
  The table of uppercase characters used for hex encoding.
• HEX_DECODE_LUT
  The lookup table of hex byte to value, used for hex decoding.
• NIL
  Represents an invalid value in the HEX_DECODE_LUT table.

Traits

• FromHex
  Types that can be decoded from a hex string.
• ToHexDeprecated
  Encoding values as hex string.
